Description
Isooctane ROTIPURAN® is a high-purity analytical solvent with a minimum assay of 99 %, specified p.a. and ACS grade. It carries CAS number 540-84-1, empirical formula C₈H₁₈, and a molar mass of 114,23 g/mol. Physical data include a density of 0,69 g/cm³, boiling point of 99,2 °C, and flash point of −12 °C, supporting safe handling planning in the laboratory. The ROTIPURAN® quality line from manufacturer Carl ROTH is established for demanding analytical applications where consistent purity and documented specifications matter. EG number 208-759-1 and UN number 1262 further aid regulatory classification and logistics. Isooctane is widely used where a low-density, volatile branched alkane is needed for extraction, dilution, or reference workflows. The glass packaging preserves product integrity during storage and dispensing in routine and research laboratory settings.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Isooctane, ROTIPURAN®, min. 99 %, p.a., ACS, 1 l, glass
What is this article?
Isooctane, ROTIPURAN®, min. 99 %, p.a., ACS, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
